“…Land use/cover types and their spatial distribution affect the water pollution status of water bodies at the basin [4,10,16]. Owing to differences in land use/cover patterns and human activity intensity, they can be significantly correlated, i.e., different land use/cover types have different pollutant outputs [45].…”

“…The influence of land use/cover type on water quality has been a concern since the 1970s [8]. Previous studies have shown that the deterioration of water quality is driven by improper land use/cover due to anthropogenic activities [9,10]. Inappropriate land use/cover has an impact on the hydrological process of the basin by causing changes in the properties of the underlying surface and soil composition [11,12].…”

Understanding the relationship between land use/cover pattern and water quality could provide guidelines for non-point source pollution and facilitate sustainable development. The previous studies mainly relate the land use/cover of the entire region to the water quality at the monitoring sites, but the water quality at monitoring sites did not totally reflect the water environment of the entire basin. In this study, the land use/cover was monitored on Google Earth Engine in Tang-Pu Reservoir basin, China. In order to reflect the water quality of the whole study area, the spatial distribution of the determinants for water quality there, i.e., the total nitrogen and total phosphorus (TN&TP), were simulated by the Soil and Water Assessment Tool (SWAT). The redundancy analysis explored the correlations between land use/cover pattern and simulated TN&TP. The results showed that: (1) From 2009 to 2019, forest was the dominant land cover, and there was little land use/cover change. The landscape fragmentation increased, and the connectivity decreased. (2) About 25% TP concentrations and nearly all the TN concentrations at the monitoring points did not reach drinking water standard, which means nitrogen and phosphorus pollution were the most serious problems. The highest output per unit TN&TP simulated by SWAT were 44.50 kg/hm2 and 9.51 kg/hm2 and occurred in areas with highly fragile landscape patterns. (3) TN&TP correlated positively with cultivated and construction land but negatively with forest. The correlation between forest and TN&TP summited at 500–700-m buffer and construction land at 100-m buffer. As the buffer size increased, the correlation between the cultivated land, and the TN weakened, while the correlation with the TP increased. TN&TP correlated positively with the Shannon’s Diversity Index and negatively with the Contagion Index. This study provides a new perspective for exporting the impact of land use/cover pattern on water quality.

“…Lockhart et al (2013) found a significant spatial correlation between groundwater nitrate contamination and land uses. Mirhosseini et al (2018) concluded that three land-use types including rangeland, irrigated, and urban area significantly affect the water quality of Zanjanroud Watershed in northwestern Iran. According to Liu et al (2021), one-to-one relations of R-squared (R 2 ) between landscape metrics and hydrochemistry variables vary from 0.32 to 0.74.…”

Source apportionment of surface water is essential for effective pollution control and sustainable water management. Physical mechanism models usually need so much data and parameters for calibration that their application for complex hydrologic condition watershed becomes difficult. However, reverse source tracing methods only based on water quality parameters present a certain subjectivity and uncertainty. In this research, additional land-use parameters were applied as an auxiliary in principal component analysis (PCA) for accurate identification of pollution sources. Thirteen water quality parameters and two meteorology parameters were used in the PCA and absolute principal component score–multiple linear regression (APCS–MLR) model to quantitatively identify potential pollution sources and their contributions to surface water pollution of the Poyang Lake Basin, in which frequent flow and sediment flux exchange with Yangtze River make the river–lake relationship complex. The results showed that urban wastewater with 34% contribution and agricultural non-point sources with 16% contribution, were the major sources of pollution in water quality. TP and NH3–N, the most serious pollutants, causing agricultural non-point source pollutions with 40% contributions and urban wastewater with 21% contributions were the major sources in the Poyang Lake Basin. Urban wastewater with 60% contributions was the major source of organic contamination. It can be concluded that with associated land-use parameters, the GIS approach with the APCS–MLR model can improve the accuracy and certainty of source apportionment, providing aid decision information for managers on protection of surface water quality.

“…For farmers, the land is a place to grow crops and a source of life, while for urban residents land is a space to build buildings such as houses, shops, and so on. The increase in the intensity of land conversion changes has a negative effect on the hydrological conditions of the watershed such as increasing peak discharge, fluctuating discharge between seasons, surface flow coefficient, and increasing sedimentation, flooding, and drought (Mirhosseini et al, 2018). On the other hand, this change in function will change the sociocultural life of the community in the watershed (Hastanti, 2017).…”

The Benggaila watershed disembogues into Kendari Bay, the upper part was dominated by forest areas and the middle and downstream parts were dominated by residential areas. Its location in the capital city of Southeast Sulawesi causes a very high change in land use and social culture in the watershed. This study aimed to determine changes in land use and community socio-cultural activities in the period 2004 to 2019. The results showed that changes in land use during that year range were very high. Changes from agricultural land and forest to the settlement were 67.4% dominate the other changes. This condition causes a shift in the socio-cultural pattern of society. The people of origin who lived in the downstream and middle of the watershed were moved to the upstream, while the immigrants stayed downstream of the watershed. These changes have also changed the patterns and methods of farming as well as behavior in utilizing forests. Soil and water conservation efforts were carried out by integrating changes in land use and the current social conditions of the community through adequate land planning and the community's mindset in utilizing the land.
